以双酚A(BPA)和均苯三甲酰氯(TMC)为单体通过界面聚合的方法在卷式炭膜上合成聚酯,制备了聚酯基炭分子筛复合气体分离膜,考察了界面聚合工艺条件如界面聚合反应时间、有机相及水相单体浓度、热处理时间、不同有机相溶剂及聚合反应次数对复合膜气体分离性能的影响,确定了最佳制备工艺条件.并通过热重(TG)、红外光谱(IR)及扫描电子显微镜(SEM)分析手段对复合膜的热稳定性、分离层的化学结构和表面形貌进行表征与分析.以最佳工艺条件下界面合成制备的聚酯膜经炭化制备了聚酯基复合炭膜,并测试其气体渗透性能,研究表明,在最佳工艺条件下制备的聚合物复合膜,其O2和N2的渗透通量分别为6.59×10-10mol/(m2·s·Pa)和2.92×10-10mol/(m2·s·Pa),O2/N2的分离系数为2.25;炭化后制备的复合炭膜其O2和N2的渗透通量分别增加为3.71×10-9mol/(m2·s·Pa)和1.19×10-9mol/(m2·s·Pa),O2/N2的分离系数则提高到3.12.
